Data Services Products: EMC-S362ANI A global model of shear-wave velocity

Summary

S362ANI, Kustowski, Ekstrom and Dziewonski (2008) , has its radial anisotropy confined to the uppermost mantle (that is, since the anisotropy is parameterized with only the four uppermost splines, it becomes very small below a depth of 250 km, and vanishes at 410 km). The 1-D reference model is “STW105”../../referencemodels/emc-stw05 .

Description

Name S362ANI
Title A global model of shear-wave velocity
Type 3-D Tomography Earth Model
Sub Type Anisotropic (in the uppermost mantle) S velocities
Year 2008
Short Description   In this model, radial anisotropy is confined to the uppermost mantle (that is, since the anisotropy is parameterized with only the four uppermost splines, it becomes very small below a depth of 250 km, and vanishes at 410 km). The 1-D reference model is “STW105”../../referencemodels/emc-stw05 .
